2. Carotid artery stenosis - Wikipedia

   en.wikipedia.org/wiki/Carotid_artery_stenosis

   The internal carotid artery supplies the brain, and the external carotid artery supplies the face. This fork is a common site for atherosclerosis, an inflammatory build-up of atheromatous plaque inside the common carotid artery, or the internal carotid arteries that causes them to narrow. [3] [4]

3. Ocular ischemic syndrome - Wikipedia

   en.wikipedia.org/wiki/Ocular_ischemic_syndrome

   Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...

4. Subclavian steal syndrome - Wikipedia

   en.wikipedia.org/wiki/Subclavian_steal_syndrome

   The proximal part of left subclavian is blocked (shaded artery). This prevents antegrade ("forward") flow to the left arm and left vertebral. As a result, flow in the left vertebral is retrograde ("backwards") towards the left arm. Flow to the brain and circle of Willis is via antegrade right and left carotid and right vertebral arteries. Specialty

5. Arterial occlusion - Wikipedia

   en.wikipedia.org/wiki/Arterial_occlusion

   Arterial occlusion is a condition involving partial or complete blockage of blood flow through an artery. Arteries are blood vessels that carry oxygenated blood to body tissues. [ 1 ] [ 2 ] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia . [ 1 ]

6. Common carotid artery - Wikipedia

   en.wikipedia.org/wiki/Common_carotid_artery

   Carotidynia is a syndrome marked by soreness of the carotid artery near the bifurcation. Carotid stenosis may occur in patients with atherosclerosis. The intima-media thickness of the carotid artery wall is a marker of subclinical atherosclerosis and it increases with age and with long-term exposure to particulate air pollution. [9]

7. Stroke - Wikipedia

   en.wikipedia.org/wiki/Stroke

   Screening for carotid artery narrowing has not been shown to be a useful test in the general population. [143] Studies of surgical intervention for carotid artery stenosis without symptoms have shown only a small decrease in the risk of stroke. [144] [145] To be beneficial, the complication rate of the surgery should be kept below 4%. Even then ...
